Simplified quadrant-partitioned array architecture and measure sequence to support mutual-coupling based calibration

摘要: A quadrant-partitioned array architecture and measurement sequence supporting mutual-coupling based calibration. The includes an of radiating elements grouped into quadrants, with a quadrant feed network intra-quadrant connected between transmitter/receiver the elements. test signal switches which provide access for testing functions, allowing to be injected one while making measurements received in adjacent quadrant. Mutual coupling module-to-module RF are performed phase up array.
